CRYOGENIC THERMAL CONDUCTIVITY TESTER OF INSULATION MATERIAL

摘要

The present invention relates to a cryogenic thermal conductivity tester of an insulation material. The cryogenic thermal conductivity tester of an insulation material comprises: a housing of a sealed structure forming an accommodation space in a vacuum state therein; a support member of a horizontal plate shape supported by a support part extended from an upper end of the housing, wherein an insulation material is installed below the same; an evaporation amount measurement unit which is positioned above the support member, receives heat entering through the insulation material from below, and evaporates by the received heat; and a heat absorbing unit which is positioned above the support member, accommodates the evaporation amount measurement unit in the middle of a lower surface thereof, and stores cryogenic liquid evaporated to block heat in all directions including heat transferred from a vertical direction of the insulation material.;COPYRIGHT KIPO 2016
